Best Companies rank: 30
As part of its employee support network, the fast-growing energy company makes the corporate jet available in times of crisis. In 2010, when an employee working on a construction project in the Caribbean needed medical attention for a pre-existing ailment, NuStar jetted him back to the states to see his personal physician. The company also dispatches the plane when needed to send employees to support a coworker in need -- flying employees from headquarters, say, to support a colleague in another location who had a death in the family.
